Do products containing Oxone® interfere with water testing?

Products containing Oxone® do not interfere with your ability to measure free chlorine (FC) in DPD testing. However, the presence of Oxone® in the water can produce a false high reading for combined chlorine (CC) if you use the standard DPD (N,N-diethyl-p-phenylenediamine) test immediately after an oxidizing treatment. For this reason, it is recommended that you either wait at least eight hours after an Oxone® treatment to test for CC, or use a test kit with reagents that eliminate Oxone® interference. Check the glossary for a list of these specially designed kits.
